Title: Power amplifier circuit
Inventor: MACHIDA FUJIO
IPC: H03F1/30
Filed: 1978-06-05
Abstract: PURPOSE:To lessen the occurrence of the pop tone by driving the next-step A-class amplifier circuit when the base voltage of the input side of the differential paired transistor becomes less than the fixed level at the ON-time of the power source. CONSTITUTION:When the power source is switched on in case the base voltage of differential paired input side transistor 5 is approximate to the forward voltage, the base voltage of paired transistor 6 becomes double the forward voltage via voltage V2. Transistor 11 lowers output 53 owing to supply of the current to the base of transistor 10. When the base voltage of transistor 5 becomes over double the forward voltage, the current begins to flow to transistor 6. Thus, transistor 11 is cut off, and output 35 increases up. Output 35 becomes steady when no difference of potential exists between capacitors 52 and 49. As the base potential of the differential paired transistors differ near the forward voltage, the pop tone is caused by the repetitive ON and OFF. This pop tone, however, can be lessened owing to steady output 53.
